View of a trade show display for Dow Chemical Company Styrofoam, featuring products from the Construction Material Sales Division. The display features samples of Styrofoam and emphasizes the product's durability, washability, and resistance to water and vermin. The tagline "If it isn't Blue-- it isn't Styrofoam" is also visible in a nod to the trademarked nature of the product.
Invented in 1941 by researchers in Dow's Chemical Physics Lab, "Styrofoam" properly refers to the Dow Chemical Company’s trademarked brand of closed-cell extruded polystyrene foam commonly used for thermal insulation and craft applications.
